UPDATED: It all has to do with Asst U.S. Attorney Daniel Saunders oversealousness in calling to testify a woman who appears to have lied on the witness stand and to the feds about Pellicano co-defendant LAPD Sgt Mark Arneson. Here is the just posted story by LA Weekly‘s Steven Mikulan, my DHD trial correspondent, who explains everything.) The jury has just been sent home, and U.S. District Court Judge Dale Fischer will rule on a mistrial motion filed by Arneson’s attorney. Arneson is charged is charged with illegally using law enforcement databases to help Hollywood P.I. Anthony Pellicano’s investigations. (CAA partners Bryan Lourd and Kevin Huvane, among others, were probed that way…) So everything is now in a state of flux. And what everyone is wondering is whether this means all five defendants or just Arneson would have to be tried over again, and therefore a do-over by all those Hollywood witnesses. Mikulan emailed me: “As of now ‘mistrial’ pertains only to Mark Arneson, although how it could effect the others remains uncertain, should he be severed from the case.”
